Установите стоимость доставки для первого товара в корзине в зависимости от зоны доставки и другую стоимость для каждого ⇐ Php

[Anonymous]

У меня есть PHP-код, который подсчитывает стоимость доставки в woocommerce на основе количества шагов в дополнение к другой стоимости, основанной на зоне доставки, сумма двух затрат дает общую стоимость доставки. что мне нужно сейчас, чтобы применить стоимость зоны доставки только к первому товару в корзине и применить стоимость на основе количества шагов к остальным товарам, начиная со второго товара в корзине.
вот мой код:
/*
WooCommerce - increase Flat rate shipping based on X quantity steps
*/

add_filter( 'woocommerce_package_rates', 'add_cost_based_on_zone_and_quantity', 10, 2 );

function add_cost_based_on_zone_and_quantity( $rates, $package ) {
$shipping_class_rates = array(
'very-light' => 20, // Shipping class slug => Quantity threshold for a step
'light' => 10,
'pre-medium' => 5,
'medium' => 3,
'post-medium' => 2,
'heavy' => 1,
'very-heavy' => 1/5,
'huge' => 1/10,
'very-huge' => 1,
);

// Define extra costs by shipping zone ID
$zone_costs = array(
'zone_1' => 80, // Adjust these with actual zone IDs and costs
'zone_2' => 100,
'zone_3' => 120,
'zone_4' => 140,
);

// Initialize an array to keep track of item counts for each shipping class
$item_counts = array();
foreach ($shipping_class_rates as $shipping_class => $qty_step) {
$item_counts[$shipping_class] = 0;
}

// Count items per shipping class
foreach ($package['contents'] as $cart_item) {
$class_id = $cart_item['data']->get_shipping_class_id();
foreach ($shipping_class_rates as $shipping_class => $qty_step) {
$term = get_term_by('slug', $shipping_class, 'product_shipping_class');
if ($class_id == $term->term_id) {
$item_counts[$shipping_class] += $cart_item['quantity'];
}
}
}

// Determine the shipping zone and retrieve additional costs
$shipping_zone = WC_Shipping_Zones::get_zone_matching_package($package);
$zone_id = $shipping_zone->get_id();

foreach ($rates as $rate_key => $rate) {
if ('flat_rate' === $rate->method_id) {
$extra_cost = isset($zone_costs['zone_' . $zone_id]) ? $zone_costs['zone_' . $zone_id] : 0;
$total_additional_cost = 0;

// Calculate the additional cost for each shipping class
foreach ($shipping_class_rates as $shipping_class => $qty_step) {
$rate_operand = ceil($item_counts[$shipping_class] / $qty_step);
$total_additional_cost += ($rate->cost * $rate_operand);
}

// Adjust the total cost
$rates[$rate_key]->cost = $total_additional_cost + $extra_cost;
}
}

return $rates;
}

Я пробовал это решение, но оно не сработало, WordPress игнорировал стоимость на основе количества шагов и добавлял только стоимость зоны доставки:
